Earthquake Safety

Federal, State, and local emergency management experts and other official preparedness organizations all agree that “Drop, Cover, and Hold On” is the appropriate action to reduce injuries during an earthquake and just as valid on the RU campus. Be aware of your enviornment and where you are on and off campus.

Know the terms that may be used in an earthquake emergency. Familiarize yourself with these terms to help identify an earthquake hazard:

Aftershock - An earthquake of similar or lesser intensity that follows the main earthquake.

Earthquake - A sudden slipping or movement of a portion of the earth’s crust, accompanied and followed by a series of vibrations.

Epicenter - The place on the earth’s surface directly above the point on the fault where the earthquake rupture began. Once fault slippage begins, it expands along the fault during the earthquake and can extend hundreds of miles before stopping.

Fault - The fracture across which displacement has occurred during an earthquake. The slippage may range from less than an inch to more than 10 yards in a severe earthquake.

Magnitude - The amount of energy released during an earthquake, which is computed from the amplitude of the seismic waves. A magnitude of 7.0 on the Richter Scale indicates an extremely strong earthquake. Each whole number on the scale represents an increase of about 30 times more energy released than the previous whole number represents. Therefore, an earthquake measuring 6.0 is about 30 times more powerful than one measuring 5.0.

Seismic Waves - Vibrations that travel outward from the earthquake fault at speeds of several miles per second. Although fault slippage directly under a structure can cause considerable damage, the vibrations of seismic waves cause most of the destruction during earthquakes.
